The Lord will raise thee up to be a holy people to himself, as he swore to thee: if thou keep the commandments of the Lord thy God, and walk in his ways.

Jehovah will establish thee unto himself a holy people as he hath sworn unto thee, if thou keep the commandments of Jehovah thy God, and walk in his ways.

'Jehovah doth establish thee to Himself for a holy people, as He hath sworn to thee, when thou keepest the commands of Jehovah thy God, and hast walked in His ways;

The Lord will keep you as a people holy to himself, as he has said to you in his oath, if you keep the orders of the Lord your God and go on walking in his ways.

Statuet te Jehova sibi in populum sanctum, quemadmodum juravit tibi, quum custodieris praecepta Jehovae Dei tui, et ambulaveris in viis ejus.

The Lord shall establish thee a holy people unto himself. This refers indeed to earthly blessings, as if Moses said, that by them would be manifested God's love towards His chosen people; still it rises higher, so that the Israelites, led on by degrees, should learn to embrace God alone, and to trust in Him according to the covenant which He had made with Abraham, "I am thy exceeding great reward." (Genesis 15:1.) For the children of Abraham were set apart and chosen to be a holy people, not only in order that, being well fed, and with a full belly, they should aspire to nothing but earthly things, but that they might be confidently assured that they would be blessed in death as well as life. Although their adoption was gratuitous, still, inasmuch as they were called unto purity, it is not without reason that God promises that what He had spoken should be sure, if by keeping the Law the Israelites themselves should continue in the covenant; as much as to say, that their sanctification should be firm and perpetual if they walked in the commandments of the Law. When He adds that it should be manifest "to [1] all people of the earth that the name of God was called upon them," it is equivalent to saying, that it should be known that they were under God's defense and patronage, and that thus they should always be safe and secure in His protection.

The oath with which God vouchsafed to confirm His promises to the patriarchs (compare Genesis 22:16; Hebrews 6:13-14) contained by implication these gifts of holiness and eminence to Israel (compare the marginal references).

The Lord shall establish thee a holy people unto himself - This is the sum of all blessings, to be made holy, and be preserved in holiness.
If thou shalt keep, etc. - Here is the solemn condition; if they did not keep God's testimonies, taking them for the regulators of their lives, and according to their direction walking in his ways, under the influence and aids of his grace, then the curses, and not the blessings, must be their portion. See Deuteronomy 28:15, etc.

And the Lord shall establish thee an holy people unto himself,.... Having separated them from all others, for his service, honour, and glory, should continue them as such, and settle them in the land, and confirm all their privileges, natural, civil, and religious. The Targum of Jonathan is,"the Word of the Lord shall establish thee, &c.''he that brought them out of Egypt, through the Red sea and wilderness, to the land of Canaan:
as he hath sworn unto thee: and to their fathers; see Deuteronomy 7:12,
if thou shall keep the commandments of the Lord thy God, and walk in his ways; by which tenure they held the land of Canaan, and their settlement and continuance in it, and enjoyment of all the good things thereof; see Isaiah 1:19.

Establish thee - Shall confirm his covenant with thee, by which he separated thee to himself as an holy and peculiar people.
